C++ Program to Print Right Triangle of Numbers in Reverse

Write a C++ program to print the right angled triangle of numbers in a reverse order using for loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows;
     
    cout << "Enter Right Triangle Numbers in Reverse Row = ";
    cin >> rows;

    cout << "Right Angled Triangle of Numbers in Reverse Pattern\n"; 

    for(i = rows; i >= 1; i--)
    {
    	for(j = rows; j >= i; j--)
		{
            cout << j << " ";
        }
        cout << "\n";
    }		
 	return 0;
}

This C++ example prints the reverse ordered numbers in the right angled triangle pattern using a while loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows;
     
    cout << "Enter Right Triangle Numbers in Reverse Row = ";
    cin >> rows;

    cout << "Right Angled Triangle of Numbers in Reverse Pattern\n"; 

    i = rows;
    while(i >= 1)
    {
        j = rows;
    	while( j >= i)
		{
            cout << j << " ";
            j--;
        }
        cout << "\n";
        i--;
    }		
 	return 0;
}

Enter Right Triangle Numbers in Reverse Row = 17
